Best Guide in 2023 to Recover Data from RAID
In this write-up, we will discuss the techniques for RAID recovery that will help you to recover data from RAID sets i.e, RAID 0, RAID 5, or RAID 6.

A damaged RAID is caused due to various issues like human errors, hardware or software failure, malware infection, mechanical errors, power interruption, failure drive, bad sectors, or abrupt system shutdown, etc.
When the RAID i.e, Redundant Array of Independent Disks array gets damaged, you become unable to access RAID volume and the data is lost. But like other drives, you can’t access or restore data from RAID hard drives independently. You need to reconstruct or set up the RAID configuration again to retrieve the lost data.
However, it’s not that simple RAID is a complex data storage technology that has multiple disks to build up one logical volume. When RAID is the build-up, Various parameters like the number of disks, parity, block size, block order, disk offset, file system, etc. are defined. You must save these RAID parameters while the construction of RAID array construction. As they become accessible when you reconstruct and recover data from a corrupt RAID.
Let’s begin with understanding why we use RAID and how we can prevent data loss and corruption in RAID.

Why do users need RAID HDD?
RAID HDD is used due to its advantages that are mentioned below:
- Provides efficient and High performance
- RAID has a fault tolerance ability that allows the system to work even when one or more hard disk drives fail.
- It gives high protection against data loss as compared to a single hard drive.
How to Recover Data From RAID?
Below are some solutions for RAID recovery to recover data from RAID. Here is some point of issues where these steps will help you recover important data files from a corrupt RAID:
- If your RAID fails, becomes inaccessible or corrupt logically.
- RAID damage due to malware or virus infection
- If RAID volumes or partitions get deleted.
Let’s see the steps that will help you to restore the important data from damaged RAID:
Step 1: Stop Using the RAID Array
Once the RAID is corrupt, failed, becomes inaccessible, avoid executing any hit & trial method, especially if your data is very crucial.
Step 2: Remove the connection of Hard Drives from the RAID Rack
Turn off the broken RAID set and Disconnect each hard drive from the RAID array. Keep the drives in a safe and secure place.
Step 3: Connect Drives with SATA/IDE Connectors
Once you disconnect drives from RAID 0, RAID 5, or RAID 6 array, connect each drive to a Windows PC. You need to use SATA/IDE connectors or a SATA/IDE to USB 3.0 converter cable or enclosure—especially if your laptop or PC motherboard has not SATA/IDE ports available.
Step 4: Ensure the Disk SMART Status & Clone Failing Drive
This is the most important step as a drive may fail due to some internal or any problem at any time, which can also lead to broken RAID. Frequent check-up of SMART status provides you a better and deeper understanding of the drive. Also, it helps you to know whether the drive is suitable or can survive a data recovery scan.
So, here we discussed a manual way to recover important data from a corrupt RAID.

Here in this blog, we discussed different solutions to recover data from RAID. You can fix the issue manually.
